Happened to me before - I just had to log out and log back in - but another variable is I logged in and refresh my entire account 24 hours later = done and solved, for me.
Is there anyway that I can get this done today? I'm trying to get something up and running within a couple of hours.
I also tried logging in in private mode (incognito) to see if that would work. No luck.
If you want to try to get something up and running today - start a new account trial - use up the 7 days free and bust our your work asap - then copy and paste each part, bit by bit, or recreate it all in your primary account.
I was trying to create multiple pages and export. It doesn't allow me to. I'm going to create a new account and do as you instructed just to get my work done.
